To examine the use of accident and emergency (A&E) services by the homeless, with particular reference to the use of psychiatric services generated by this attendance.
A retrospective study of attendance registers at a large A&E department over an eight year period, during which there were 566 separate attendances by homeless patients out of a total of 421 237 adult attendances (1.3 per 1000).
There was no significant change in rates of attendances over the eight year period (P = 0.41), in the broad demographic details of the groups, or in the use of psychiatric services.
There has been no significant increase in the use of A&E services by homeless people in the population studied over the eight year period. Several possible explanations for this are given.
研究无家可归者对事故与急救（A&E）服务的使用情况，尤其关注此类就诊引发的精神科服务使用情况。
对一家大型急诊科八年期间的就诊登记进行回顾性研究，在此期间，无家可归患者共有566次单独就诊，而成年患者总就诊次数为421237次（每1000人中有1.3次）。
在八年期间，就诊率、各群体的大致人口统计学细节或精神科服务的使用情况均无显著变化（P = 0.41）。
在所研究的人群中，八年期间无家可归者对A&E服务的使用没有显著增加。文中给出了对此的几种可能解释。
